Long survey about groceries....44 min. Foreign speaking lady

Called about a food store survey 2 days ago. Said "no thanks" and hung up.  They called back again tonight.  

The call came in @ 6:30 pm 04/30/2014. The caller I.D. read SSI, I learned that the call was generated in Lynchburg, VA.
When calls come in on my home # and I don't recognize the name on my caller I.D. I answer using my professional voice,
the caller hangs up the majority of the time. I feel the SSI caller I D name is being used for the purpose of having the elderly believe the call is from Social Security Insurance.

They called several times in the last few days without leaving a message.

Have received repeated calls today without a human on the other end, just a loud and repeated beeping sound as if a computer is attempting to connect. We have also gotten similar beeping messages left on the answering machine. Caller ID reads SSI. No idea how to contact the company to stop calls.
